Rio 2016: Did Olympics chiefs SPLIT UP Bolt and De Grasse after pair joked on the track?
FANS hoping for another display of Usain Bolt and Andre De Grasse's "bromance" were disappointed to find them separated in the 200m final.
Usain Bolt was separated from friendly rival Andre De Grasse
The photos sent the internet into a spin, with many admiring the mens' "bromance".
But in last night's final, the friendly rivals were broken up when officials placed American runner Lashawn Merritt in lane four.
Bolt and De Grasse were either side of him in lanes five and six.
The sprinters are good friends despite competing against each other regularly
Fans on Twitter were outraged, with one commenting: "How dare Merritt get in between Bolt and De Grasse, he will never kill the bromance."
Bolt, however, was pleased with his position as lane six offers one of the smoothest and straightest runs.
He told reporters before the race that he "was hoping for lane six to be able to run as best as I can”.

The pair were separated by American runner Lashawn Merritt
Dr Laura Charalambous, a lecturer at the University of Bedfordshire, explains that the runners' lanes are allocated using a series of draws based on the athletes' semi-final performance.
A computer draws names from the four with the fastest times to determine lanes three, four, five and six.
The three sprinters had the best-semi final rankings, which made them eligible for the key positions.
Bolt won his second gold of the Games
Bolt went on to win the race, putting him one step closer to the "treble-treble".
The 29-year-old was disappointed not to have beaten his world-record time of 19.19, though he confidently admitted: "I've proven to the world that I'm the greatest."
De Grasse settled for silver, just days after he came close to beating Bolt in the semi-final.
The two will face off again tonight in the 4x100m relay, which will be the Jamaican's final ever Olympic race.
